Yes that exactly the bonding hash I am using layer3+4. I have another server where I run simple libvirt/KVM in a similar scenario e it does balance the traffic well between all physical interfaces on the host as there are many individual connections to the VM. But my question was if there was anything that hard limit any VM traffic to 1Gb unless you change and also what the speed the is shown on the interface is related to ? 1Gb, 10Gb or if you can set that specifically ?

Hello.
Is there any limitation of bandwidth for a Virtual Machine per default ?
I have a host with a bonding of 3 x 1Gb and the VM is connected to that bonding. On the Engine interface on the VM status I see "Network" and it has a percentage and a tiny graph. What that percentage is related to ? 1Gb ? 3Gb ? 10Gb ?
Is there anything that has to be done in order the VM can achieve speeds over 1Gbps ?
To the external network, you cannot easily achieve >1Gb, unless you open multiple connections that will go over multiple physical NICs. It depends on the bond hashing policy. layer3+4 might make it easier to achieve. This is not very different than a connection from the host. (I think UDP should be easier, but it's less interesting?)
VM to VM traffic should easily overcome 1Gbps. Y.
